So you can dial it up THROUGH your current alt and it won't capture as you spin it? Assuming the MCP Alt was originally set below you to allow descent in Path?
We don't use that feature and I'd guess it's because of all the varied RNP's in Alaska. There probably wouldn't be a consistent point in the profile where you could set the missed so it could get skipped. For LNAV/VNAV we just always set it when executing the missed... it's always at the same place in that profile: Gear Up, Set Missed App Alt".
